Heidi Klum isn't about to play nice when the wellbeing of her kids is at stake. Although the Project Runway host and her estranged spouse, Seal, had seemed to remain on amicable terms for the sake of their four kids, they now are gearing up for a fierce custody battle in the wake of shocking revelations about the "Kiss from a Rose" singer's criminal past, Star has learned.

"The original agreement was that Heidi would have primary custody and Seal could visit at any time," a source explains. "But since the breakup was announced [on Jan. 22], Heidi has been looking to pack up their home in Brentwood and go back to New York."
